Prevent Death "Cheat" cheat for The Sims 3

If your Sim has a death flower in their inventory when they die, they'll give it to the grim reaper in exchange for their soul. You can usually find a death flower at the graveyard in the beginning. Harvest the plant and keep this on your Sim. If they happen to die by fire, drowning or any other preventable way, your Sim will hand over the flower and live on.
